(Continued)
11-197
Bushings must be in servocylinder
before installing bolt; otherwise,
damage to component will result.
NOTE
Impedance bolts are installed in flight
control connections. These bolts are
self-retaining and require a special
nut and torque (Task 1-13).
1.
Remove bolt (1), two washers (2 and 3), and nut
(4) from servocylinder (5).
2.
Position control valve boot (6), large end up on
servocylinder (5). Stretch boot over housing (7)
and slide up until small end of boot is in groove
(8) above lugs (9).
3.
Install strap (10) on small end of boot (6). Tighten
strap 5 to 9 pounds pull force. Use strap (E375)
and strap tool.
4.
Install strap (11) on large end of boot (6). Tighten
strap to 15 to 25 pounds pull force. Use strap
(E375) and strap tool.
5.
Position link (12) in lugs (9) of servocylinder (5).
Install bolt (1), two washers (2 and 3), and nut
(4). Torque nut to 30 to 45 inch-pounds. Install
cotter pin (13).
6.
Check bolt (1). Bolt shall not rotate with torque
less than 10 inch-pounds. There shall be no
axial looseness. If bolt rotates or is loose, add
washer under nut, and repeat step 5.
